STEPHEN C. Henkel has a fixation on bicycles. He even wrote a book on the subject called Bikes ‘A How-to-do-it Guide to Selection, Care, Repair, Maintenance, Decoration, Safety and Fun on your Bicycle.’ And with a degree in Mechanical Engineering from Princeton I guess he was the right person to do that. The cool thing about the book is that the author also made the illustrations. For instance, he drew types of handlebars and the all the parts of a rear wheel hub. The Chatham Press published the book in 1972.
